TB 2.6.0.7 cannot get HUD working

I have a new TB 2.6.0.7 server set up and HUD server installed and running:

[trixbox1.localdomain etc]# ps aux | grep hud
root 2869 0.1 2.5 57560 52272 ? SNs Jun05 3:14 /usr/local/fonality/hud/hudlite-server

I have HUD Admin installed and running on the TB GUI

I have installed a hudlite client on a workstation but cannot get it to connect to the server.

I have got the correct username (SIP202) and password from the Admin and put it into to the Hudlite client with the standard Server password of 'password' but cannot connect.

I am also seeing this on the asterisk CLI:

== Connect attempt from '127.0.0.1' unable to authenticate

which goes away when I stop the HUD server ... so must be HUD doing it.

/etc/hosts file looks fine:

127.0.0.1 trixbox1.localdomain trixbox1 localhost.localdomain localhost

I have trawled the forums and tried every suggestion but cannot get it working!

This looks like a different password for the HUD Server to me?

Guidance would be appreciated.

Thanks
